Application filed March 9, 1907. Serial No. 361/184.

To all whom it may concern:

Be it known that l, TnnorrnLUs BROWN,

a citizen of the United States, residing at.

2 is the same with the beater shield withdrawn, and Fig. 3 is a top View of the beater.

Similar reference letters and figures refer to similar parts in the different views.

My invention relates to a beater shield for the front of the beater of a manure spreader which, when in position between the beater and the load of manure, prevents the pressure of the load against the beater to means for withdrawing said shield from between the beater and the load when the beater is to be operated, and to means for scraping the movable apron or bottom of the spreader, and my invention comprises the construction and arrangement of parts as hereinafter described and pointed out in the annexed claims.

Referring to the accompanying drawings 1 is the body of the manure spreader provided with a bottom consisting of a traveling apron 2 and a beater 13, mounted on a shaft 4 jour- 5 naled in hubs 5, held in posts 6 attached to the frame of the spreader. The beater 3 may be revolved in any suitable manner common to manure spreaders of similar construction. Pivoted on studs 7 mounted on the sides of the spreader above the beater in brackets 8 are bell cranks 9, 9, t0 the arms 10 of which are attached rods 11, 11, leading to the front of the manure spreader and pivotally attached to arms 11 on a rock shaft 11 which is operated from the seat by means of the lever handle 12. Journaled on the hubs 5 between the V osts 6 and the end of the beater are bell cran s 13, whose arms 14 extend toward the front of the manure spreader and within its sides. Pivotally attached to the ends of the arms 14; is a shield 15 extending downwardly and rearwardly beneath the beater, its .ower end resting upon a support 16 which extends transversely across the spreader and holds the shield 15 out of connot in operation.

1 tact with the traveling apron The sup port 16 is preferably in the form of a blade with a thin forward edge 1.6 adapted to scrape the upper surface of the apron 2 and clear any manure which sticks to the apron and escapes the beater. The shield 15 is shown curved, concentric with the beater and is preferably constructed of sheet metal, but its form and method of construction may be changed without departing from my invention. The other arms 17 of the bell crank 13 are attached by links 18 to the arms 19 of the bell cranks 9.

The operation of my improved beater shield is as follows: By rocking the shaft 11 the bell cranks 9 are rocked, thereby rocking the bell cranks 13 through the connecting links 18 and withdrawing the shield 15 beneath the beater. The shield 15 is guided by the su port 16 until the shield is moved clear of t 1e body of the manure spreader when the shield swings on its pivoted connection with the arms 14 and rests against the support 16, as shown in Fig. 2.

By a reverse movement of the shaft 11 the shield is drawn up underneath the beater into the position shown in Fig. 1 in which position it is designed to shield the beater from the load of manure when the beater is The rods 11 are pivoted to the arms 11 in such position that when the shield is raised in front of the beater the arms 11" are below the center of the rock shaft 11 which looks the shield in its elevated position. l/Vhen the beater is to be operated the shield is withdrawn as above described. The mass of manure cleared from the apron by the scraper passes over I the scraper and into the path of the beater teeth as the beater is revolved.

I claim,

1. A manure spreader, having a beater and a movable shield in front of said beater, supporting arms pivotally attached to the 1 upper edge of said shield, a transverse support for said shield below said beater, and means for rocking said arms downward to carry the upper edge of said shield beyond said transverse support.

with a beater, of rocking arms, a movable shield with its upper edge pivotally attached to said rocking arms, means for rocking said arms downward to withdraw said shield beneath said beater, said arms arranged to 2. In a manure spreader, the combination ermit said shield to rock on its pivot away trom said heater when said shield is moved beyond the body of said manure spreader.

3. In a manure spreader, the combination with a heater and rocking arms, of a movable shield with its upper edge pivotally attached to said rocking arms, means for rocking said arms downward to withdraw said shield heneath said heater, and a transverse scraper beneath said heater arranged to act as a support and guide for the free end of said shield.

4. In a manure spreader, the combination with a heater and rocking arms, of a movable shield With its upper edge pivotally attached to said rocking arms, means for rocking said arms downward to withdraw said shield heneath said heater, means for guiding said shield concentric to said heater until it has passed the end of the manure spreader, said l guiding means then arranged to permit said shield to swing on its pivot away from said I beater.

5. A manure spreader, having a heater and a movable apron, a movable shield in front of said heater, supporting arms pivotally attached. to the upper edge of said shield, a transverse support for said shield below said heater and with one edge adapted to scrape the upper surface of said apron, and means for rocking said arms downward to carry the upper edge of said shield beyond said transverse support.
